      <title>CVE-2026-39822 — Root escape via symlink plus trailing slash in os</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-39822</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Go standard library os&lt;/p&gt;
&lt;p&gt;On Unix systems, opening a file in an os.Root improperly follows symlinks to locations outside of the Root when the final path component of the a path is a symbolic link and the path ends in /. For example, &amp;#39;root.Open(&amp;#34;symlink/&amp;#34;)&amp;#39; will open &amp;#34;symlink&amp;#34; even when &amp;#34;symlink&amp;#34; is a symbolic link pointing outside of the root.&lt;/p&gt;</description>
